Tom Carter is obsessed with toy trains and this frustrates his wife, Elizabeth carter. During breakfast, Elizabeth ridicules her husband due to his childhood behavior. Tom is not happy with his despicable wife and he goes to work. No longer does he departs from the house than Elizabeth gets a call from Dorothy, their neighbor. Dorothy informs her that a stranger is wandering around Elizabeth’s house. Before she confirms the identity of the stranger, a doorbell rings. A young man enters and identifies himself as Glen. Glen tells Elizabeth that he is her abandoned baby boy to who she gave birth while still at school.
Glen tells Elizabeth that he yearns for motherly love as a child. Soon after, mother and son start behaving flirtatiously. The behavior reflects Freud’s idea of the Oedipus complex where a baby boy is subconsciously sexually attracted to her mother. Apparently, Glen starts playing with Tom’s train toys but Elizabeth cautions him. Subsequently, Elizabeth asks Glen to sing for her. The song makes her fall asleep. When she wakes up, she finds Glen has gone. Fear engulfs her and she calls Dorothy. Elizabeth confesses to her neighbor how she was defiled by a man in her sixteen and gave birth to a baby boy. Later, her parents sold off the boy.
Tom returns from work and finds the two women talking. Elizabeth is rambling about a baby. However, her husband is unconcerned and only calls it a game. Dorothy looks confused and storms out of the house. Tom scolds her wife and warns her against inviting other people into their games. Elizabeth seems completely delusional, but Tom is only focused on his toys.
